A square carpet of 5m is laid on the floor of a room length 5m50cm and breadth 6m. find the area of the floor that is not carpeted

Answer»

Given
length of side of carpet(s) = 5m

therefore AR (carpet) = s^2
= 5^2
=5×5
=25 m^2

Length of room(l) = 5m 50 cm
breadth (b) = 6

therefore ar (room) = l×b
=5.5 × 6 [ 5m 50 cm can written as 5.5 m]
= 33 m^2

area of remaining room after PUTTING carpet
= ar ( room) - ar ( carpet)
= 33 - 25
= 8m^2.

Therefore the area of remaining room = 8m^2
